A nurse is preparing to suction secretions from a patient who has a new tracheostomy. Which of the following actions should the nurse plan to take?
Use a resuscitation bag with 80% oxygen prior to the procedure.
Select a suction catheter that is half the size of the lumen.
Place the end of the suction catheter in water-soluble lubricant.
Adjust the wall suction apparatus to a pressure of 170 mm Hg.
The Correct Answer is B
Choice A rationale: Using a resuscitation bag with 80% oxygen prior to the procedure is inappropriate. While pre-oxygenation is important before suctioning to prevent hypoxia, the oxygen concentration should be 100%, not 80%. Normal oxygen saturation levels are 95% to 100%. Pre-oxygenating with 100% oxygen ensures the patient maintains adequate oxygenation during the brief suctioning period. Using 80% oxygen does not fully optimize oxygen reserves for this purpose.
Choice B rationale: Selecting a suction catheter that is half the size of the tracheostomy lumen is appropriate. This size prevents excessive occlusion of the airway, ensuring adequate airflow during suctioning. The correct catheter size minimizes trauma to the tracheal mucosa and prevents hypoxia. The catheter should not exceed 50% of the tracheostomy diameter to maintain proper airway function, making this the correct action for safe and effective suctioning.
Choice C rationale
Placing the end of the suction catheter in water-soluble lubricant is not recommended. This could introduce bacteria into the airway and increase the risk of infection.
Choice D rationale
Adjusting the wall suction apparatus to a pressure of 170 mm Hg is not correct. The recommended suction pressure for adults is usually between 80 and 120 mm Hg. Suctioning at too high a pressure can cause trauma to the airway.

Correct Answer is A
Explanation
Choice A rationale
Using a bed exit alarm system is a common intervention to minimize the risk of injury in patients with dementia. These systems alert staff when a patient attempts to leave the bed, allowing for timely intervention to prevent falls.
Choice B rationale
Raising four side rails while the patient is in bed is not a recommended practice. This could be considered a form of restraint and could increase the risk of injury if the patient attempts to climb over the rails.
Choice C rationale
Applying one soft wrist restraint is not a recommended practice for patients with dementia. Restraints should be used as a last resort and only when necessary for the patient’s safety.
Choice D rationale
Dimming the lights in the patient’s room is not a recommended practice to minimize the risk of injury in patients with dementia. Adequate lighting can help prevent falls and other accidents.
Correct Answer is A
Explanation
Choice A rationale
Auscultating lung sounds is the priority when monitoring for adverse effects of administering IV fluids. Fluid overload can lead to pulmonary edema, which would be detected by abnormal lung sounds such as crackles.
Choice B rationale
While measuring urine output is important to assess kidney function and fluid balance, it is not the priority in this case.
Choice C rationale
Monitoring blood pressure readings is important when administering IV fluids, but it is not the priority in this case.
Choice D rationale
Monitoring electrolyte levels is important when administering IV fluids, but it is not the priority in this case.
